This is a manual hybrid automatic transmission on this vehicle!

Automatic transmission fault warning message on dash?

Will not change up through he gears?

System fault code in transmission ECM is: 171AH/5914 undocumented code?

System fault codes in engine management ECM are:
U1133 LIN network the reversible alternator is absent?
U1134 LIN network no communication with voltage retaining device?
U1400 Alternator LIN network registering of a fault on the LIN network?
P16A3 control unit monitoring fault on starter inhibitor (Level 2)

Initially Checked the charging system & all seems O.K & charging!!!

All engine management fault codes erase but return after road test!

Fault code in transmission ECM will not erase!

Any ideas?

Found charging system is discharging the battery at idle only from first starting the vehicle! If you blip the throttle the system starts charging????

This animal has a controller at the battery positive terminal! Many bodies are buried deep in this MOFO
